STAY-ROLLER FGR SLlDlNG DOORS.

SPECIFICATION forming part of Letters Patent No. 290,521, dated December 18, 1883.

Application filed September 18, 18F3.

To all whom, it 771065;] concern-.-

Be it known that I, IVARREN M. Bnmnnn- HOFF, a citizen of the United States, residing at Auburn, in the county of Cayuga and State of New Yorlg'have invented new and useful Improvements in Stay Rollers for Sliding Doors, of which the following is a specification.

This invention relates to stay-rollers for sliding doors, whichare composed of a support or shank carrying at one end a roller, and adapted to be driven or screwed atits other end into a building, whereby a guideway is created between the wall and the roller to receive and guide the lower edge of a sliding door.

The object of mypresent invention is to provide novel and simple means for looking or retaining the support or shank against turning or rotating, thereby holding the stay-roller in a fixed position relative to the door, and avoiding the displacement from proper position as a guard to prevent the door from swinging outward.

The invention also has for its object to provide novel and simple means to vary and determine the depth of penetration of the support or shank into the building, so that a guideway of a determined width can be secured between the wall of the building and the stay'roller, and whereby the width of said guideway can be varied, in order to accommo date doors of varying thicknesses, and also to compensate for the wall of a building being out of perpendicular. These objects I accomplish in the mannerand by the means hereinafter described, and pointed out in the claims, reference being had to the accompanying drawings, in which- Figure l is a perspective view of a stayroller constructed in accordance with my invention; Fig. 2, a sectional view of Fig. 1; Fig. 8, a perspective view, showing a modification of my invention; and Fig. 4, a transverse sectional view of Fig. 3.

Referring to the drawings, the number 1 indicates the roller-supp orting shank, which may be of any desired form in cross-section throughout its length, and have ascrew-thread, 2, at one end, for screwing it into a building, or be simply pointed, so that it may be driven in by a hammer or other instrument, while the other (Yo model.)

end of the shank is constructed with a journal-arm, 3, arranged at right angles, or approximately so, on which is loosely arranged a stay-roller, 4, against which the sliding door bears in its sliding movements. The shank is transversely perforated along its length, preferably for a distance at the center of the same, and, as shown in Fig. l, the perforation consists of a circular aperture, 5, such perforation being for the purpose of receiving apin, 6, the ends of which project from opposite sides of the shank. hen the shank is driven or screwed into position, the pin limits its depth of penetration by coming in contact with the wall, after which the pin is rigidly secured to the wall by passing staples 7 over its ends and driving them tightly down; but instead of staples it will be obvious that any other fastening device can be employed, it only being essential to securely fasten the pin to the wall, so that the shank is rigidly held or locked against turning or rotating, so that the stay-roller is securely retained in a fixed position relative to the lower edge of the door, and hence always prevented from displacement.

In Fig. 1 I have shown several apertures, 5, at determined distances apart, the object of which is to permit the pin to be inserted into one or the other for the purpose of varying the distance between the wall and the roller and changing the capacity of the guideway, so as to adapt it to doors of different thicknesses, while at the same time, by changing the pin from one aperture to the other, the stay-roller can be made to stand at agrcater or less dis tance from the wall, to compensate for any inclination of the wall of the building. I have shown the transverse apertures and the pin as circular; but obviously the apertures may be of any shape in outline-such as square, polygonal, or rectangularand the pin may be of corresponding shape in cross-section, or any other shape which will permit it to be passed through any one of the apertures and hold or lock the shank against turning or rotating.

In Figs. 3 and 4 I have shown a modification of my invention, in which, however, the

same results are accomplished as in the other construction, and by reference to Fig. 3 it will be seen that the transverse perforation is in the IOC form of a longitudinal slot for receiving a narrow flat pin or plate, preferably having end perforations, 8, for receiving screws by which to rigidly secure the pin or plate in place on the wall of the building, to hold or look the shank against turning or rotating.

In order to retain the pin or plate in the longitudinal slot, it is twisted immediately outside of the slot to form shoulders 9, and at the same time such twisting causes the pin or plate to present flat surfaces to the wall of the building. The pin or plate can obviously be adjusted along the length of the slot, to serve as a gage in determining the depth of penetration of the shank, and, if desired, the pin or plate may be fastened in' a fixed position after adjustment in the slot.

In a stay-roller embodying in its structure the characteristics herein set forth and shown, or their mechanical equivalents, the shanklocking pin or plate can be adjusted along the length of the shank, and may be held in a fixed position when desired, and thus the pin or plate not only serves to lock the shank against turning, but it also determines the 2 5 depth of penetration of the shank, and enables the width of the guiding-space between the wall and stay-roller to be Varied for the purpose of accommodating doors of different thicknesses, and also compensating for any 30 inclination of the wall of the building.

Having thus described my invention, what I claim is- A stay-roller for sliding doors, consisting of a shank carrying a stay-roller to prevent out- 3 5 Ward swinging of the door, said shank having a transverse perforation to receive alocking-pin for preventing the shank from turning, substantially as described.

In testimony whereof I have hereunto set 40
